With the success of Es’hail-1 and the growing demand for a range of satellite services in the MENA region, we are currently working on the manufacture of our second satellite Es’hail-2.Scheduled for launch in 2018, this high-powered, advanced satellite will further boost broadband delivery, broadcasting and global connectivity in Qatar, the entire region and beyond.Es’hail-2 is being manufactured in Japan by MELCO (Mitsubishi Electric Corporation).Es’hail-2 will have Ku-band [24 transponders] and Ka-band [11 transponders] capabilities and support TV distribution, telecoms and government services to strategic stakeholders and commercial customers who value broadcasting independence, interference resilience, quality of service and wide geographical coverage. The satellite will also provide greater capability for anti-jamming protection and redundancy and back-up for Es’hail-1.Es’hail-2 will also provide the first Radio Amateur Satellite Corporation (AMSAT) geostationary communication capability that connects users across the visible globe in one single hop and in real-time.It will allow also the AMSAT community to validate and demonstrate their DVB standard.
Es'hailSat has selected SpaceX to launch their Es'hail-2 comsat on a Falcon-9 rocket in the fourth quarter of 2016 from Cape Canaveral.

Es'hail-2 reached a major milestone in spacecraft completion, with successful completion of critical acoustic and vibration tests.

Any signs of the satellite's departure from MELCO, or impending delivery to SpaceX facilities at Cape Canaveral?I assume delivery will be via An-124?
This tweet from April says the satellite will be launched in Q4 2018, Is there a reason it got pumped up to September ? or was that just a mistake from Ben Cooper who announced it on his website ?https://twitter.com/eshailsat/status/990186733366120448
B1050 will likely be tasked with lifting communications satellite Es’hail-2 in very late August or early September.

SFN is also reporting NET August for Es'hail. I would agree that this looks very unlikely at this point based on the lack of FCC permits.https://spaceflightnow.com/launch-schedule/
This flight and CRS-16 might be from different pads. There was an FCC filing for a launch from 39A (which doesn't guarantee it's from 39A, but that seems to be the plan when it was filed.)
The next SpaceX Falcon 9 rocket from Cape Canaveral will launch the Es'Hail-2 communication satellite for Qatar from pad 39A on November TBD.
The flight for Es'hail 2
Es'hailSat confirmed a Q4 2018 NET earlier today. https://twitter.com/eshailsat/status/1024898547165093890Edit: just realized that "NET earlier today" is sneaky lil' palindrome
Es’hail-2 is set to go into space this fall or early winter aboard a SpaceX vehicle; a specific launch date is not available.
Given that Es'hail will not use a booster for the third time, it would have to be 1047.2 or a 105x.It's 16 days away - surely we should be able to uncover this.

...It seems their launch capacity exceeds their current market...
Going to assume no static fire today?
They aborted the 9 AM static fire attempt this morning, but since the window lasts until 3 PM, could they try again soon? Or will the static fire be scrubbed until tomorrow?
Is there a mission logo/patch for this mission?

What?? Did you see the first stage pass some sort of balloon on its way down?
Quote from: billh on 11/15/2018 07:54 pmWhat?? Did you see the first stage pass some sort of balloon on its way down?I saw it, too. It was an object of some sort.
It was ice or something that came off the booster.
Quote from: matthewkantar on 11/15/2018 07:59 pmIt was ice or something that came off the booster.It seems unlikely that any ice build-up could have made it all the way to MECO. Someone ask Elon what his unidentified falling object is.
Video of it going by.
People are posting comments and pics of the object under Elon's twitter post.
Satellite picked up a noticeable rotation upon separation. Would that be expected? Seemed higher than past missions.
Quote from: DaveJes1979 on 11/15/2018 08:14 pmPeople are posting comments and pics of the object under Elon's twitter post.And people wonder why Shotwell doesn't have a Twitter account.
The USAF has posted a definitive identification of the object. Just a weather balloon.
A few notes for trajectory geeks. Seemed like a lower than previous parking orbit - 165 km at seco-1, 188 km at seco-2. Second stage should re-enter quickly.Second stage second cutoff at 34356 km/hr = 9849 m/s. Add 402 m/s for Earth rotation, so 10251 m/s. This is almost exactly what they need for a GTO apogee, so neither sub nor super synchronous.Last question is inclination. This payload was supposed to be about 3000 kg. The slightly heavier Bangabandhu (3700 kg) got down to a 19.3 degree inclination. This should do better. A quick guess shows reducing the mass from 3700 kg to 3000 kg should give an extra 80 m/s. With this, SpaceX should be able to reduce the inclination to 18.4 degrees.So final prediction 188 x 36000 km, inclined 18.4o, deficit 1640 m/s to GEO.

A few seconds later you had a second object passing on the other side of the rocket. Barely visible.

The fairings seen as the booster catches up and passes them? The screen captures posted by CraigLieb sure look like a fairing.
The satellite weighed around 11,700 pounds (5,300 kilograms) with its on-board propellants, according to Zoubair Kachri, Es’hailSat’s technical vice president.
Quote from: marsbase on 11/16/2018 01:45 amThe fairings seen as the booster catches up and passes them? The screen captures posted by CraigLieb sure look like a fairing.Seems unlikely. Fairings are jettisoned about a minute after stage separation. During that time the booster is already in free fall while the second stage carries the fairings downrange and accelerates them by an additional 1000 km/hr or so.

Anyone know what the object is by front left landing leg? Some new safing gadget? I do not remember seeing this before. Something to do with octograbber ops?
Was it normal for the rainbirds to go to full flow that late? (This can be seen in just about every shot shown in this video.) I know they don't go full flow during the engine startup sequence, but it seems like they ramped up to full flow about one second too late, based on plume impingment.

It does appear late at first glance, but they output a LOT of water. That amount of water could damage the rocket, so they wait to go full power until the rocket is clears the rainbird height.

The only times I saw them activate were during the Falcon Heavy Test Flight and Bangabandhu 1. They weren’t used for Es’hail 2.

This has to be one of, if not the fastest times to go horizontal after arrival!
Quote from: RocketLover0119 on 11/21/2018 03:55 pmThis has to be one of, if not the fastest times to go horizontal after arrival!Best I can tell, it's the second fastest to horizontal, at ~1.96 days after docking. Beating it is Merah Putih at ~1.69 days. More here.
